Description

Technical Field

[0001] The utility model relates to the technical field of openers, in particular to a roving end opener. Background Art

[0002] The existing roving head loosening machine will produce a large amount of short yarn and scraps when in use. Most of them are extracted by fans. However, the short yarn and scraps are light in weight and easily drift to the outside. It is impossible to effectively collect the short yarn and scraps, which is inconvenient to use. A roving head loosening machine with application number "CN202122900392.5" preliminarily loosens the roving through the relative movement between the cotton feeding roller and the roving. At the same time, the motor drives the cylinder and the combing roller to rotate in the opposite direction to fully loosen the roving. The loosened yarn is discharged through the discharge port, and the broken short yarn falls onto the partition. At the same time, the fan discharges the air in the opener body, so that the suction pipe sucks the fallen short yarn to the bottom of the partition, and the water pump draws out the clean water in the water tank and sprays it through the atomizing nozzle. When the water flows through the turbine, it can drive the rotating tube to rotate through the turbine, and can spray the short yarn passing through the suction pipe, so that the short yarn and broken material can fall to the bottom of the opener body to prevent the short yarn and broken material from scattering to the outside, and can effectively collect the short yarn and broken material generated by the opener body.

[0003] However, when the above scheme is in use, the counterweight block drives the top plate to press the cotton feeding roller tightly. But when the opener body is hit, the counterweight block shifts, causing the top plate to lose its effect. At the same time, the scraper knife is prone to wear during use. The above scheme is not convenient for replacing the scraper knife. Utility Model Content
